Suppose that Bill, a resident of the U.S., buys software from a company in Japan. Explain why and in what directions this changes U.S. net exports and U.S. net capital outflow. ANS: The purchase of a foreign good by a U.S. resident is a U.S. import. Since net exports = exports - imports, net exports decrease. Bill pays for the software with U.S. dollars so that the Japanese have obtained more U.S. assets. Since, net capital outflow = the amount of foreign assets acquired by domestic residents - domestic assets acquired by foreign residents, the increase in foreign holdings of dollars by Japanese residents decreases U.S. net capital outflow. DIF: 3 REF: 31-1 TOP: Net capital outflow Net exports

2072 Chapter 31 /Open-Economy Macroeconomics: Basic Concepts 3. Why are net exports and net capital outflow always equal? ANS: Net exports and net capital outflow are always equal because every international transaction is an exchange. When a seller country transfers a good or service to a buyer country, the buyer country gives up some asset to pay for this good or service. The value of that asset equals the value of goods and services sold. Hence, the net value of goods and services sold by a country (NX) must equal the net value of assets acquired (NCO). DIF: 3 REF: 31-1 TOP: Net capital outflow Net exports 4. Colonial America had little industry and so had mostly raw materials to export. At the same time, there were many opportunities to purchase capital goods and earn a high rate of return because there was little existing capital so that the marginal product of capital was relatively high. What does this suggest about net exports and net capital outflow in colonial America? ANS: Net exports were negative because the value of exports was low, and the colonies imported capital goods. If net exports were negative, net capital outflow must also have been negative. Net capital outflow would have been negative because the colonies sold stocks, bonds, and other domestic assets to buy capital goods from abroad. DIF: 2 REF: 31-1 TOP: Net capital outflow Net exports 5. Derive the relation between savings, domestic investment, and net capital outflow using the national income accounting identity. ANS: Start from the national income accounting identity, (1) Y = C + I + G + NX. Recall from Chapter 25 that national saving is the income that is left after paying for current consumption and government expenditure, (2) S = Y - C - G. Rearranging, (1) we obtain Y - C - G = I + NX, and substituting in (2) (3) S = I + NX. Because net exports also equal net capital outflow, we can also write this equation as (4) S = I + NCO. DIF: 3 REF: 31-1 TOP: National income accounts 6. Suppose that a country has $120 billion of national saving, and $80 billion of domestic investment. Is this possible? Where did the other $40 billion of national savings go? ANS: This is possible for an open economy. The remaining $40 billion is for net capital outflow in the form of purchases of foreign-owned assets by this country s residents. Domestic residents can save by buying U.S. assets or by buying foreign assets. DIF: 2 REF: 31-1 TOP: National savings 7. How do the nominal exchange rate and the real exchange rate differ? ANS: The nominal exchange rate is the rate at which a person can trade the currency of one country for the currency of another. The real exchange rate is the rate at which a person can trade the goods and services of one country for the goods and services of another. DIF: 2 REF: 31-2 TOP: Nominal exchange rate Real exchange rate 8. How do we find the real exchange rate from the nominal exchange rate?

If the exchange rate is 1.25 euros per dollar, what is the real exchange rate? ANS: The real exchange rate = nominal exchange rate Domestic Price/Foreign price = 1.25 euros per dollar 20 dollars/25 euros = 1. DIF: 2 REF: 31-2 TOP: Purchasing-power parity 10. What is the logic behind the theory of purchasing-power parity? ANS: The logic behind purchasing-power parity is the law of one price, which asserts that a good must sell for the same price in all locations. If the price for a good is higher in one market than in another, someone can make a profit by purchasing the good where it is relatively cheap, and selling the good where it is relatively expensive. This process of arbitrage leads to an equalization of prices for the good in all locations. If purchasing power parity holds, the amount of dollars it takes to buy a good in the U.S. should buy enough foreign currency to buy the same good in a foreign country. DIF: 2 REF: 31-3 TOP: Arbitrage Purchasing-power parity 11. Suppose that a U.S. dollar buys more gold in Australia than it buys in Russia. What does purchasing-power parity imply should happen? ANS: People can make a profit by buying gold in Australia and selling it in Russia. Purchases in Australia drive down the amount of gold a dollar can buy there. Sales in Russia drive up the amount of gold a dollar can buy there. Purchasing-power parity theory claims that this should continue until the dollar can buy the same amount of gold anywhere. DIF: 2 REF: 31-3 TOP: Arbitrage Purchasing-power parity 12. What does purchasing-power parity imply about the real exchange rate? ANS: That it is equal to one. The number of dollars it takes to buy goods in the U.S.buys enough foreign currency to buy the same amount of goods in a foreign country. DIF: 1 REF: 31-3 TOP: Purchasing-power parity Real exchange rate 13. According to purchasing-power parity, what is the relationship between changes in price levels between two countries and changes in nominal exchange rates? ANS: Purchasing-power parity asserts that the nominal exchange rate is equal to the foreign price level divided by the domestic price level. If the domestic price level rises more than the foreign price level, the domestic currency depreciates. If the foreign price level rises more than the domestic price level, the domestic currency appreciates. DIF: 2 REF: 31-3 TOP: Purchasing-power parity 14. Can purchasing-power parity be used to explain the fact that the U.S. dollar has depreciated by more than 50 percent against the German mark between 1970 and 1998, but appreciated by more than 100 percent against the Italian lira during the same period? Defend your answer. ANS: The theory of purchasing-power parity suggests that Italy must have experienced much more inflation than the United States while Germany must have experienced much less inflation. In fact, that is exactly what has happened. DIF: 2 REF: 31-3 TOP: Purchasing-power parity

2074 Chapter 31 /Open-Economy Macroeconomics: Basic Concepts 15. Suppose that money supply growth continues to be higher in Turkey than it is in the United States. What does purchasing-power parity imply will happen to the real and to the nominal exchange rate? ANS: Higher money growth leads to higher prices, so prices will rise more in Turkey than in the United States. Under purchasing-power parity, this has no affect on the real exchange rate. However, in order for a dollar to buy as many goods in Turkey as it buys in the United States when prices are rising faster in Turkey, the nominal exchange rate must be rising so that a dollar buys more Turkish lira. DIF: 2 REF: 31-3 TOP: Purchasing-power parity 16. Assuming all other things equal, what would happen to the U.S. dollar real exchange rate under each of the following circumstances? a. The U.S. nominal exchange rate depreciates. b. U.S. domestic prices increase. c. Prices in the rest of the world rise. ANS: a. The U.S. dollar real exchange rate depreciates. b. The U.S. dollar real exchange rate appreciates. c. The U.S. dollar real exchange rate depreciates. DIF: 2 REF: 31-3 TOP: Real exchange rate 17. Under what circumstances does purchasing-power parity explain how exchange rates are determined, and why is it not completely accurate? ANS: Purchasing-power parity works well in helping us explain long-term trends in exchange rates, and in explaining what happens to exchange rates during hyperinflation. It is not completely accurate because (1) not all goods are easily traded, and (2) even tradable goods are not always perfect substitutes when they are produced in different countries. DIF: 2 REF: 31-3 TOP: Purchasing-power parity 18. Suppose a lobster supper in Maine costs fewer dollars than a Lobster supper in Paris, France. Explain why this is inconsistent with purchasing-power parity and explain why the inconsistency may exist. ANS: According to purchasing-power parity, a dollar should buy the same amount of goods everywhere in the world. The inconsistency may exist because lobsters have to be transported to Paris. Price differences can also persist because goods are not perfect substitutes. While eating lobster gazing at the Maine coastline may be a pleasurable experience, eating well-prepared lobster in a fancy French restaurant may be an experience people would be willing to pay more for.
